Homebru....burr only forms when the wheel grinds to the very very end of the shoulder. Shoulder and edge are same angle. They are the same.
If you grind the shoulder at one angle then grind the edge at another, then it is very hard to get a burr.
Hold BH at one angle on the wheel make 3 light passes and check for burr, then make another pass at same angle ,check for bur , then make another pass at same angle ,check for burr, then make another pass at same angle check for burr..on and on till??...eventually after 1 of these passes, the wheel will grind at the very very end of the blade and roll a burr over.....
try it that..let me know if that helps..........remember same angle
